' more particularly to means for adapting a machine of this typeembodying a rotary traverseroll for winding packages of differentlengths or for simultaneously winding a plurality of packages of lesslength than the'full traverse of the roll.

cated having means for reversing the direction of traverse .of the yarnintermediate the ends 0 I the traverse-roll.

Another object of the. invention is to provide a winding machine of thetype indicated in which a single traverse-roll is adapted tosimultaneously'traverse multiple yarns to wind a plurality of packages.

Another object of the invention is to provide a winding machine of thetype indicated having adjustable means for reversing the direction oftraverse of the yarn in either direction at any of the plurality ofcrossings of the oppositely extending helical yarn paths on thetraverse-roll by which the yarn is guided.

Still another object of the invention is to provide in a winding machineadjustable means for reversing the direction of traverse of the yarnwhich iswsimple in structure and arrangement, efllcient and positive inperforming its intended function, and. adapted to be applied to standardtypes of winding machlnes without alteration in the structure thereof.

Further objects of the invention are set forth in the followingspecification which describes a preferred form of construction of thedevice, by way'of example, as illustrated by the accompanying drawings.

In the. drawings:

, Fig. 4 is a view similar to Figs. 2 and 3 showing another modifiedarrangement of the traverse-reversing means for simultaneously windingthree separate packages.

Winding machines of the described in the Reece patent,'referred toabove, have gone into extensive use because of the .increased speed atwhich the yarn can be wound and the facility with which the machine maybe operated. In machines of this type a rotary roll having continuous orinterrupted grooves, ribs or other like helical guiding means on itsperiphery continuously traverses the yarn back and forth on the packagein oppositely directed helical paths with the direction of traversereversed at either end of the roll. Each roll is thus adapted to wind asingle package of predetermined length.

The present invention relates generally to a stop or abutment mountedopposite the traverseroll, and preferably adjustable longitudinally withrespect thereto, to adapt it to cooperate with the helical guiding meansof the roll to control the extent of traverse of the yarn thereby. Theyarn engages the stop to reverse its direction of traverse intermediatethe ends of the Either one stop may be employed to wind a single packageof predetermined length less than that of the traverse-roll; or aplurality of stops may be provided for winding several packages from aplurality of supplies. The stops are preferably so constructed andarranged as to permit them to he slid along their fixed support to anoperative position and fastened in the double gang type comprising aplurality of d winding units arranged in series along the opposite sidesof a horizontal frame or bed 2 supported at its opposite ends bysuitable legs, not herein shown. Spaced along the top of the bed I are aseries of uprights l which mount bearings 5 for the driving shafts andother parts of the winding mechanism, two opposite units being locatedbetween each pair of brackets. but only one unit being herein shown. 1 1

The winding mechanism of eachunit com prises two principal elementanamely, the windingvmandrel or spindle 9 on which the yarn- 1 receiveror cop-tube C is rotatably supported; and .the' roll H for rotating theyarn-receiver and in which is embodied the means for traversing the yarnback and forth axially of the packtype illustrated and be understood,however, that the present inventlon is adapted for use with other formsof traversing rolls incorporating a similar principal of operation andhaving either interrupted grooves or projecting ribs which direct theyarn in its helical path; or with machines wherein the package is drivenby contact with a drive-roll and the yarn traversed by a separatetraverseroll; or with machines having any other suitable arrangement ofthe winding elements.

The term traverse-roll" as hereinafter used in the specification andclaims is thus intended to include any type of roll or drum fortraversing the yarn back and forth on the package, whether employed as aseparate element or constituting the drive-roll as herein illustrated.

In the form of construction shown'in the present drawings the roll H iscarried on and rotated by a horizontal shaft ll journaled in thebearings 5 onthe uprights 4; the shaft it being extended throughout thewhole: length of the gang machine to carry a plurality of rolls for anydesired number of winding units. It wili be understood that in thepreferred form or" the machine a second parallel shaft, not hereinshown, is journaled in bearings in the uprights 4 at the opposite sideof the machine and carries another series of rolls.

The present machine is shown as adapted for winding packages oicylindrical form with the yarn built up on a suitable axial core orreceiver, a paper or fiber cop-tube C for this purpose being illustratedin the drawings as mounted to rotate on the winding-spindle or mandrel8. In other instances, however, the package may take the form of atruncated cone and in such case the traverse-roll may be correspondinglyshaped. A suitable cop-holder i0, herein shown as comprising acylindrical sleeve, is rotatably mounted on the spindle 9, beingprovided with any usual means for gripping the cop-tube C thereto. Inother instances the holder may be of tapered form to adapt it to receiveconical tubes.

The winding-spindle 9 is swiveled at the forward end of a weighted arml6 which is pivotally supported at its rearward end on a horizontal rodIT to adapt the surface of the yarn-receiver C, and the periphery of thepackage P, to be held in contact with the periphery oi the roll As theyarn is built up on the cop-tube C it forces the latter upwardly withthe arm swinging on its pivot I! in the manner common to machines of thepresent type. Although not herein shown in detail, a suitable steppingmechanism is employed with each unit of the machine to automaticallyarrest the winding operation by raising the package away from the rollThe stopping mechanism is controlled by a pivoted wire lever l8 held ininoperative position by the yarn being wound.

A tension-device I3 mounted on a bracket 20 is located intermediate theends of the traverseroll II and positioned at a distance outwardly anddownwardly therefrom. The tension-device I9 is preferably of theself-threading type comprising a pair of rotatable tension-disks 2|.Wire threading balls 22 and 23 are so shaped that a yarn drawnthereacross will be automatically 1 guided into an eye 24 in the ball 22and between the tension-disks 2|.

In accordance with the embodiment of the invention illustrated in Figs.1 and 2 of the drawings, a single stop or abutment is adjustably mountedclosely adjacent the traverse-roll II to adapt it to engage thetraversing yarn to reverse its direction of traverse at any one of theplurality of crossings of the helical paths through which the strand isguided. The stop 30 may take any suitable form or shape, being hereinillustrated as a cylindrical post or pin with a smooth rounded surfacefor engaging the yarn. The stop 30 may be mounted on any suitablesupport which may constitute a standard part of the machine or beapplied thereto as an attachment. As herein illustrated, the stop 30 ismounted on a horizontally-extending support 3| which is in the form of arod having its opposite ends held in sheet-metal clamps 33 fastened tothe uprights 4 by screws 34. The clamps 33 are bent around to embracethe ends of the rod 3| which are clamped therein by means of bolts 35.The stop 30 has a transverse bore 36 through which the supporting rod 3|extends to mount the stop for adjustment longitudinally oi thetraverse-roll II. An axial, threaded bore 3lis also provided in the stop3|) for receiving a setscrew 38 which is set up against the rod 3| to-'clamp the stop in adjusted position thereon. By

loosening the set-screw 38 the stop 80 may be moved along the supportingrod 3| to any desired operative position intermediate the ends of theroll ii or to an inoperative position outwardly beyond the ends thereof.One form of the in vention having now been described in detail, its modeof operation will be next explained.

The strand of yarn y is drawn off from a bobbin or other source ofsupply, not herein shown,

laid across the threading bail 22, the rod 8| and roll II, and its endsecured to the cop-tube C. If a package of standard length is to bewound a cop-tube C of a length substantially equal to that of the rollII is applied to the holder H! on the winding-spindle 9 at the end oi.the arm IS. The arm I6 is then lowered into position to place thesurface of the cop-tube C against the roll ii. The roll H is rotatedcontinuously and the cop-tube C rotated therefrom to wind the yarn ontoits periphery. As the yarn y is drawn across the threading ball 22 it iscaused to automatically enter the eye 24 and between the tension-disks2| to both guide and tension the strand as it leads to the roll As theyarn draws across the rod 3| it is picked up by the groove I! or l3, orsuch other means as provided on the periphery of the roll H, to traverseit back and forth along the tube C to commence the winding of thepackage.

To adapt the machine to wind packages of a length shorter than that forwhich the standard roll is designed, a spindle and cop-tube holder orappropriate length are substituted for the standard spindle and holder.The stop 30 is then adjusted on the supporting rod- 3| to a positionslightly in advance of a particular intersection a: or the oppositelydirected helical yarn paths on the roll Ii, being spaced from theterminus of the grooves in the roll a distance corresponding to thelength of the package to be wound. To accomplish this adjustment thesetscrew 38 is loosened to permit the stop 30 to clamp the stop fixedlyin place. Preferably, the

angular position of the stop II should be such that the stop will extendoutwardly from the rod 3| at right-angles to the direction of feed ofthe yarn.

With the roll ll rotating in'a counterclockwise direction, as viewed inFig. 1, the groove II causes the yarn y to be traversed from therighthand end of the roll toward theleft ,until it engages the stop SIas indicated by the dotand-dash lines in "Fig. 2. As a result of thisengagement the yarny is restrained from further traverse to the left andthe length of yarn extending between the stop and roll II is deflectedto the right as it reaches the crossing a: of the grooves l2 and I3,thereby causing it to be diverted into the return groove l2. The yarn yis then traversed toward the right-hand end of the traverse-roll to theposition indicated by dash lines in Fig. .2 where its direction is againreversed as it again enters the groove It. The yarn y is thus traversedback and forth throughout a portion. only of the length of the roll I Ito build a package P of a length less than that of the roll. Fig. 2illustrates the machine as adapted for building a package P ofapproximately two-thirds the length of the roll II; but

it will be understood that packages of several other lengths may bewound with: the type of roll here shownby adjusting the stop 30 to aposition slightly in advance of any one ofthe five crossings of the.oppositely directed helical paths formed by the grooves l2 and I3.

If the yarn y breaks or becomes exhausted during the winding of apackage, and when a full package P has been completed, the stoppingmechanism acts to lift the arm It to move the package away from theroll. the yarn y may then be repaired, or the completed package dofledand the machine prepared for a subsequent winding operation. The stop-30 is preferably made of such length that when the arm i6 is lifted toits uppermost position the yarn y will still be in engagement with thestop as indicated by dash lines in Fig. 1.

In the embodiment of the invention illustrated in Fig. 3 of thedrawings, a pair of stops 30 are mounted on the supporting rod '3! toadapt them to function for reversing the direction of traverse of aplurality of yarn strands y and y intermediate the ends of the roll IIto simultaneously wind two packages P' and 1. As herein shown the stopsit are positioned at thelongitudinal centerof the roll and inabuttingrelationship. Two yarn strands 1/ and 3 are fed from independent-sourcesto lead across the rod II on opposite sides of the pair of stops 30 withtheir ends attached either to .a single cop-tube or a pair of tubes C,injthe usual manner. As the roll II is rotated the septratestrands 1 and14* feed through the traversing grooves and i3 at-the opposite ends. ofthe roll, as indicated by dash lines in Fig. 3, and are caused to betraversed toward'the center of the roll until they engage the stops 30..As explained with respect to the first form of construction illustratedin Figs. 1 and 2,-the lengths of yarn between the stops II and the roll;H are deflected as'they approach the center crossing z of the oppositelyunderstood that with the last described arrange- The break in ment thestops 30 may be adjusted to a position in conjunction with any of theother crossings in Fig. 4 of the drawings, two pairs of stops 0 aremounted on the supporting rod II to adapt the machine to wind threeseparate packages in spaced relationship on the spindle 0; one packagebeing wound at the center of the roll H between the pairs of stops andthe other two at the opposite ends of the roll. In this form ofconstruction the grooves l2 and I3 on the roll II have a greater numberof crossings and the stops 30 of one pair are adjusted to a PO? sitionopposite the crossings :c" and 2: toward the left-hand end of the rollwhile those of the opposite pair are positioned opposite the crossings xand :1." toward the right-hand end of the roll. sources, arefed acrossthe rod 3|. through the grooves l2 and I! at the opposite ends of theroll u, and a third strand 11 1s fed between the 25 inner stops of theopposite pairs. Rotation of the roll ll causes the yarn strandsy'. and11' to be traversed from the outer ends of the roll ll toward its centeruntil they engage the outermost steps 30 of each pair and theirdirection of traverse is then reversed as explained with respect to Fig.3. The yarn strand 1! is traversed in the groove it from the cross ng 23toward the .crossing- :1: until it engages t e inner stop 30 of theright-hand pair which causes it to be diverted into the groove ll toreverse its direction of traverse. The yarn 1/ is then traversed by thegroove II in the\ opposite direction, or toward the left, until itengages the inner stop 30 of the left-hand pairt whichgin turn causes itto be diverted to the pposite groove 12. It

.will also be'understood hat packages of still dlflerent dimensions maybe wound on the machine by adjusting the stops to other positions.

It will be observed from the i'oregoing'that the present inventionprovides a novel and simple arrangement of means'ior reversing thedirection of traverse of the yarn intermediate. the ends Yarn strands 1!and 11" from independent of a rotary traverse-roll to adapt the machineingfrom the spirit or scope of, the invention.
